Selection and dosage of defoamers
The lower the surface tension of water-based paint, the smaller the free energy required for the system to form foam, and the easier it is to produce foam. However, such foam is not necessarily stable. Only when the system contains surfactant that can form an elastic film, for defoamer, first pay at

The "anti foaming" effect of defoamers on water-based inks
DefoamerIntroduction: Defoamers in water-based inks can quickly remove bubbles from the system and also have an anti foaming effect. Water based defoamers are not only environmentally friendly with low usage, but also do not affect the performance of water-based inks, while improving the surface pro
